The influence of the Moon on cannabis seed germination is scientifically debated, but it has been considered for centuries in traditional agriculture and by many growers.

Scientific Perspective

From a scientific point of view, the direct effects of lunar gravity and weak moonlight on plants are considered very small. So far, there is no clear scientific evidence showing a measurable influence of the lunar cycle on the germination or growth of cannabis.

Traditional Practice

• Waxing Moon: Traditionally regarded as an optimal time for germination and planting. It is believed to promote water uptake as well as above-ground plant growth.
• Waning Moon: Traditionally associated more with root care, soil work, and pruning.

Conclusion

For many growers, the lunar calendar remains a long-established tradition. Although its effects have not been conclusively proven scientifically, following the lunar cycle is unlikely to cause problems as long as the basic germination conditions are maintained. These include sufficient moisture, a stable temperature of 22–25 °C, and cleanliness.

Growers who wish to take the lunar cycle into account can choose to begin germination during the waxing Moon.
